Quick question, I have a 2010 LF Lyman LTD, I love the thing behind boat so I only ride it there, thing is I've barely ridden boat in the past 2 years, 10 sets max.
Will the board be ok moth balling it or should I just bring it to the cable?

I've heard people reference cores breaking down and turning to dust over time, is that true or is it fine to hang it on the shelf for long periods?

If you've got a dry area out of the sun it'll be just fine. Core's breaking down is often associated with riding… the repeat of bend, flex, impact, snap, recoil causes the core to breakdown. Sitting idle indoors out of the sun it'll last just fine.
